Methods and apparatus for performing impedance matching

A communication device, comprising:

• a matching network including variable reactance elements;
• a controller coupled with the matching network;
• wherein the controller performs operations comprising:
• determining a first voltage standing wave ratio (VSWR);
• selecting a VSWR circle from among a group of VSWR circles based on the first VSWR;
• identifying a group of sets of tuning settings for the variable reactance elements based on each set of tuning settings of the group of sets of tuning settings being associated with the VSWR circle;
• and
• selecting a set of tuning settings from among the group of sets of tuning settings responsive to a second VSWR determined for the set of tuning settings satisfying a VSWR threshold.

A non-transitory computer-readable storage medium comprising computer instructions which, responsive to being executed by a processor, cause the processor to perform operations comprising:

• determining a first voltage standing wave ratio (VSWR);
• selecting a VSWR circle from among a group of VSWR circles based on the first VSWR;
• identifying a group of sets of tuning settings for variable reactance elements of a matching network, wherein the identifying of the group of sets of tuning settings is based on each set of tuning settings of the group of sets of tuning settings being associated with the VSWR circle;
• and
• selecting a set of tuning settings from among the group of sets of tuning settings responsive to a second VSWR determined for the set of tuning settings satisfying a VSWR threshold.
